INCORPORATED, OF PITTSBURG, PENNSYL- APPARATUS FOR MAKING UP TRAINS-SPECIFICATION forming part of Letters Patent No. 783,070, dated February21, 1905. Application filed July 20, 1904. Serial No. 217,421.

To all whom it may concern.-

Be it known that I, WILLIAM J. PATTERSON, a resident of Pittsburg, inthe county of Allegheny and State of Pennsylvania, have invented a newand useful Improvement in Apparatus for Making up Trains; and I dohereby declare the following to be a full, clear, and exact descriptionthereof.

My invention relates to car-hauls, and more especially to apparatus formaking up trains of empty cars in connection with such car-hauls.

The object of my invention is to provide for the making up of trains ofempty cars without the jarring and jolting of the cars, and therebyreducing the wear and tear on the same.

To these ends my invention comprises, generally stated, an inclinedchain haul adapted .to engage the empty cars and a substantiallyhorizontal portion at the lower end of said chain haul, with means onsaid chain haul for advanclng the car when it reaches such a point alonga substantially level track, whereby each empty car is advancedsubstantially a carslength, while the Whole train is advanced the samedistance each time.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure 1 is a side view of my improved carhaul. Fig. 2 is a planview thereof. Fig. 3 is an enlarged detail view of one end of thecarhaul, showing the horizontal portion adapted to advance the emptycars along the horizontal track.

Like numerals indicate like parts in each.

In the drawings the uphaul-chain 2 passes around the wheels 3 and 4E,and the downhaulchain 5 passes around the wheels 6 and 7. These chainsmay be driven in any suitable manner. The track 8 is the downhaul-trackand the track 9 the uphaul-track, both tracks uniting in the track 10 atthe upper end of the haul. In the car-haul illustrated the loaded carsare taken up by the uphaul-chain 2, while the empty cars are taken downby the downhaul-chain 5.

At the lower end of the downhaul-chain 5 is the substantially horizontalsection 12,which extends for a suitable distance parallel with thehorizontal track 13.

I may employ any suitable form of a carhaul chain, that shown comprisingthe stationary projections 14 and the pivotal or movable projections 15.The movable projections 15 project above the stationary projections 14and are adapted to advance the car on the short upgrade 16, while therigid projections 14 are adapted to engage and control the car in itsdescent.

The empty cars after they have been unloaded are run back over the track10 onto the downhaul-track and when they reach the downhaul-chain arefirst engaged by the movable projections 15 and advanced up the slightgrade 16 until they begin to descend the downhaul 5. At this point therigid projections are engaged by the cars and control their speed indescending. IVhen the empty car reaches the horizontal portion of thechain haul, the speed of the car decreases, and the pivotal projections15 then come into engagement with a suitable projection on the car, andsaid car is advanced along the horizontal track until the pivotalprojection engaging therewith passes around the wheel at the bottom ofthe car-haul, and is thus disengaged from the empty car. The next car inits descent will be engaged in the same manner by pivotal projections atthe horizontal portion of the chain and said. car will be advancedsufficiently to move the car previously lowered about a cars length, theaction of said chain being to advance the cars at an even positive speedalong the horizontal track, so that the cars as they come down arepushed against the preceding cars without jarring or jolting, and inthis manner the train is made up by advancing the cars a cars lengtheach time until the entire train has been completed.

What I claim is 1. In apparatus for making up trains of cars, thecombination of a suitable chain haul having a main inclined portion, aninclined track corresponding thereto, means for controlling the descentof the cars by said chain haul, a substantially horizontal portion ofthe lower end of said chain haul, a track portion corresponding thereto,and means for advancing said cars by said chain haul along saidlast-named track portion a cars length each time.

2. In apparatus for making up trains of cars, the combination ofasuitable chain haul having a main inclined portion, an inclined trackcorresponding thereto, means for controlling the descent of the cars bysaid chain haul, a substantially horizontal portion at the lower end ofsaid chain haul, a track portion corresponding thereto,and projectionson said chain adapted to engage the cars when said horizontal trackportion is reached.

3. 1n apparatus for making up trains of cars, the combination of asuitable chain haul having a main lnclined portion, an lncllned trackcorresponding thereto, projections OIL pivotal projections on said.chain adapted to 5 engage the cars at said horizontal track portion.

I testimony whereof I, the said WILLIAM J. PATTERSON, have hereunto setmy hand.
